Why don’t researchers publish their raw data for the advance if science?

These are some of the many criticisms received by all fields of science for a long time. If I read an article on Psychological Science and am sceptical of their results, or if I want to apply another statistical techniques to see if the results remain convincing to me, I can’t. I need to run another experiment. Or if I want to conduct a meta-analysis, maybe having other researcher’s raw data is better than just the mean/CI they report in journals.

If scientists’ mission is for public good and for the advancement of knowledge, why don’t they publish their results in raw (of course they need to remove research participants’ privacy information). They shouldn’t be afraid of others’ criticising their work. Only truth can endure the testing of time.

Nowadays, with the prevalence (and low price) of online storage platform and sophisticated database management, why don’t they do it for the public’s good?

EDIT: by raw data, I mean to make the dataset public and accessible to everyone (well… at least researchers)
